UN TED STA ES P I Y ASSIGNOR TO THE Bonn contrary, Inc, A CORPORATION or new YORK j comm) srnme CUSHION Application area June 15, The present invention has for its object a simple and novel'means'for'tying together corresponding intermediate coils of bed spring structures of the vertical, coiled Spring type, whereby the structure is stifiened against lateral swaying without impairment of its cushioningqualities.

The various features of noveltywhereby my invention is characterized will herein after'be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be had tofthe following detailed description taken in connection with the accompanying drawings, wherein: 7 Figure 1 is a top plan view, showing more or less diagrammatically a bedspring of a well known type towhich my invention is applied, only fragments of the cushion p'ortion being shown; Fig. 2-is a horizontal secg tion, on a much larger scale than Fig. 1, through, a corner of thespring, looking downward, the section being taken approximately on line 2-2 of Fig.3; Fig. 3 is an edge View of a corner of the spring, on the same scale as '2; Fig. 4c is a section taken-approximately on line -4 of Fig. 3; and Figs. '5 and 6 are sections, on a still larger scale, taken, respectively, on lines 5 5and 66 of Fig. 2L

Referring to the 'drawings,1 represents a heavy bottom frame from wh'ich rise vertical coiled springs 2 arranged in rows that extend transversely of the supporting frame and'als'o longitudinally. The upper coils of F the springs may be connected'together by small, diagonal helical springs i or in any suitable way. I In fact, all of the structure thus far described is old and well known in various forms to which my invention is applicable.

In accordance with my invention,corre-' sponding intermediate coils I of all of the springs in each row are connected together by ties'so that each spring will be aided by all i u of the other springsin resisting lateral or However, accordthese ties arefof such a character thateach spring maybe compressed and expanded without meeting any appreciable resistance from theotherv springs or the ties. This result is brought about by swaying movements.

hinging the, actual ties, which are the parts extending across the spaces between adjacent springs, to the springs.

Since there are a great many vertical springs in a bed spring, inany hinges are required, and I have, therefore, produceda simple and novel arrangement for efiectively hinging the ties to the springs in suchza manner that relative movements of the hinge joints will not make audible sounds. H

The ties themsel' es may conveniently be made of light wire and be attached to the springs by simple anchoring plates. In. the arrangement shown, the anchoring members are in the form of sheet metal plates 5 cut away. at the center so as to permit them to surround the springs. In removing the metal from the centers of the plates, I leavediametricallyopposed tongues 6. .In applying an anchoring plate to a'spring, it is run along the wire of the spring until broughtinto the plane of the intermediate coil, indicated at A .in the-drawings,

to which it is to be secured, the tongues overlying such coil. The tongues are then bent around the wire of. the spring andserve securely to holdthe plate. At four points along the periphery or edge of {the plate, spaced 90 downwardly into tubesforming hinge ears each plate being fastened to its-spring in such a manner that ahinge ear or a set of liinging ears lies on each side thereof nearest the two wire;' thefwidth of each frame being only slightly greater than the length of one of the hinge ears or sets of ears; whereby each short frame element of, ,a tie may serve also as a;

1 hinge 'pintle, being surrounded by oneof 1 the hingele'ars or setsofears, a o g I It will be seen that each spring, exceptthose of the outermost row, is, at the center. ,ofaa square at whose corners are four other springs, and whose sides formangles 0M5 with the longitudinal and ;transverse axesof apart, are tonguesbent i the 1 spring assembly so that the tieielements form diagonals ofthis -square-and each may may be bent around the wire of the ,frame 9v to each of said intermediate swing at either end about a horizontal axis at right angles to the length thereof.

There is preferably employed another frame 9, similar to the frame 3, but lying in the plane of the anchoring plates. One ear 10 or set of ears on the outer side of each of the anchoring plates on the outermost springs so as to hold this frame to the springs. V

- In order to reduce the number of wires close to the edge of the spring structure as a whole, the tie elements 11 between the springs of the outermost rows may be similar to" those that have been described, except that one long side or frame member is left off, giving these ties the form of a single wirehaving its ends bent laterally in the same direction to form hinge pintles.

The vertical springs 2 are supported from the bottom frame 1 in any suitable way as, for example, by members or elements 13 extending across the frame 1 from side to side and members or elements 14 extending across the frame from end to end; there being an element or member 13 and an element or member 14 crossing each other underneath each spring.

It is believed that the operation, as well as the construction of my improvements, has been sufiiciently explained. It will be seen from the left-hand side of Fig. 5, however, that the tie. wires may swing up and down relatively to their anchoring plates, so that the anchoring plate on any spring that must sustain a heavy load may remain horizontal as the spring is compressed and the plate moves down.

While I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the'exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the definitions of my invention constituting the appended claims.

I claim: V

1. The combination with a spring cushion comprising a bottom spring-supporting frame and a superstructure including verticalcoiled springs mounted on the frame and arranged in transverse and longitudinal rows, of ties extending from an intermediate coil of each spring to. the corresponding coils ofthe adjacent springs in each transverse and longitudinal row, a ring-like metal plate lying outside of and surrounding and secured coils, each plate having at theperiphery hinge ears each registering with the corresponding tie and ex tending transversely thereto, and the 'end portions of the ties extending laterally into said hingejears.

2. The combination with a spring cushion containing vertical coiled springs arranged in transverse andlongitudinal rows whereby surroun ding comprising a bottom each inner spring is at the center of a square at the four corners of which are four other springs, of ring-like metal plates lying outside of and surrounding and fixed to corresponding intermediate coils of the springs, a ie in the form of a long, narrow rectangular frame extending from each spring in the center of a square to each spring of the corner of that square, and hinge ears on each plate the adjacent narrow frame members of the ties radiating therefrom.

3. The combination with a spring cushion spring-supporting frame, vertical coiled springs mounted thereon and arranged in transverse and longitudinal rows, and a top frame extending along and connected with the upper ends of the outermost springs of a tiestructure between the springs comprising a' ring-like metal plate lying outside of and surrounding and fastened to each spring, ties extending from each plate to the plates associated with the four adjacent springs in the corresponding longitudinal and transverse rows, and hinge connections between the plates and the ties, the hinge axes being horizontal and those for the longitudinal ties being transverse to the cushion while those for the transverse ties are longitudinal of the cushion.

4. The combination with a spring cushion comprising a bottom spring-supporting frame and a superstructure including vertical coiled springs mounted on the bottom frame and arranged in transverse and longitudinal rows, of ring-like metal plates surrounding andfixed to corresponding intermediate coils of the springs, each plate having thereon four hinge ears on the sides facing four surroundingsprings, and ties connecting the hinge ears on each spring with the near hinge ears on the four surrounding springs.
